Hello, 

I'm using PDF Viewer to load a byte[] from my file 

 

file info : 28 pages

size : 3,4MB

It takes almost 20 seconds to load my pdf... theres an option to optimize this?

Code:

@if (arquivopdf != null)
{
    <div class="mt-n7">

        <TelerikPdfViewer @ref="@PdfViewerRef"
                          Width="100%"
                          Height="800px"
                          Data="arquivopdf">
            <PdfViewerToolBar>

                <PdfViewerToolBarZoomTool />

                <PdfViewerToolBarCustomTool>
                    <MudIconButton Icon="@Icons.Material.Filled.Download" Size="Size.Small" Color="Color.Dark" OnClick="BaixarArquivo" Style="@ocultarImprimir" />
                </PdfViewerToolBarCustomTool>

                <PdfViewerToolBarCustomTool>
                    <MudIconButton Icon="@Icons.Material.Filled.MobileScreenShare" Size="Size.Small" Color="Color.Dark" OnClick="() => AbrirEncaminhar()" Style="@ocultarEncaminhar" />
                </PdfViewerToolBarCustomTool>

                <PdfViewerToolBarCustomTool>
                    <MudIconButton Icon="@Icons.Material.Filled.ArrowBack" Disabled="@disableAnterior" Size="Size.Small" Color="Color.Dark" Style="@ocultarBtnAnterior" OnClick="() => CarregarAnterior()" />
                </PdfViewerToolBarCustomTool>

                <PdfViewerToolBarCustomTool>
                    <MudIconButton Icon="@Icons.Material.Filled.ArrowForward" Disabled="@disableProximo" Size="Size.Small" Color="Color.Dark" Style="@ocultarBtnProximo" OnClick="() => CarregarProximo()" />
                </PdfViewerToolBarCustomTool>

                <PdfViewerToolBarCustomTool>
                    <MudIconButton Icon="@Icons.Material.Filled.Close" Size="Size.Small" Color="Color.Dark" OnClick="()=> Cancel()" />
                </PdfViewerToolBarCustomTool>

            </PdfViewerToolBar>
        </TelerikPdfViewer>

    </div>
}

    protected override async Task OnInitializedAsync()
    {
        _relatorio = await _RelatorioService.ObterRelatorioPorId(Id);

        arquivopdf = _relatorio.Arquivo;
    }

Hi Carlos,

I confirm that we already have an open bug report regarding the described problem with the loading time: PDF Viewer initial document load is very slow. I have voted there on your behalf and raised the priority of this issue. By subscribing to the bug report, you will receive email notifications for any updates on its status.

I am sorry for any inconvenience the issue may have caused you.

In the interim, if any viable workarounds surface, I will promptly share them at the above-provided link.
